<P>PROBLEM TO BE SOLVED: To provide a centrifugal separator in which the groove of unevenness formed to a rotor adapter can be detected stably in a short time. <P>SOLUTION: The dividing frequency signal, in which the oscillation output of a Colpitts oscillator circuit 5 is divided, is counted by a high-speed clock; data corresponding to the rotor hole of a recessed groove and the rotor plate surface of a plane are generated by the change of the difference value of a counted value, and are memorized in a memory 83; a microcomputer 8 performs filter processing to the numerical data, and detects the recessed groove by comparing the generated binary numerical envelope data with former numerical data. The disposition pattern of the detected recessed groove is encoded binary, and identifies the type of a rotor 1 by being compared with the code table that is memorized beforehand. <P>COPYRIGHT: (C)2013,JPO&INPIT |
